Application le. January 20, 1912. Serial No. 672,513.

T 0 all whom 'it may concern Be .it known that l, SYLvEsTEn GEORGE S'rnvnns, a citizen of the United States, residin at Duluth, in the county ot' hit. Louis and tate of Minnesota, have invented cer tain new and useful llnproveinent-s in Motor-Driven lrIand-Cultivators, of which the following is a specification, reference being had therein to the accoinpnying drawing.

My invention relates to improvements in motor driven hand oultivators.

The object of my invention is to provide a hand cultivator which is driven by a Inotor and the cultivating means driven by the same motor independent of the driving. means, whereby the soil over which the cultivator passes may be cultivated to any desired extent by al single passage of cultiva tor over the soil.

Another object of my invention is to prof vide a motor driven hand cultivator having the cultivating teeth or elements extending laterally beyond the-traction Wheels in an improved manner whereby the soil may be cultivated as close to the row of growing plants as desired Without the traction Wheels injuring' the plants.

nother object of my invention is "to provide a cultivator-of this character in which volving cultivator and are dependent there-` upon for their traction powers. Others areV propelled by traction Wheels and draw their cultivating teeth or `elements through the soil and still other-sare propelled by some outside force, such es hand or. horse powerA and cultivating the soil through the niediuin oit their traction elements, such `as :revolving disk or the like, or independent cultivating elements. as the case may it is readily seen that the cultiveting properties o' such ,sprockets T 7.

endless sproeii 1 tached thereto the cnltlvstor tee machines are limited to a single operation oi' the device, that is for a more 'thorough culti vation of the soil, the machine must he made to 'pass over the ground repeatedly, whereas in my cnltivator in which the eultiv..-.ng elements ere operated independent ci the traction pow@ the soil he cultivated to any state of lineness with hut a single 'pas sage of the cultivetor thus-dispensng with a great amount of lalior in passing repeat edly over the saine ground to destroy plant lite and properly cultivate the ground, i

ln the accompanying dra-Wingmlligure l is e side elevation of my improved cultivstor. Fig. 2 is a top plan view with the oil tank and the battery loon removed 'in order that the mechanism below' may he niore readily illustrated.

,Referring new te the drawing" and l represent the 'two traction Wheels of the etilt-ivator which are .fined to the axle Ei, and carried by said axle in the frame 3, which may be of any desired form, but preferably of that shown. The forward end of the freine extends upwardly at Il. which snpf ports the motor 5 and has its reerivz'ird lower portion extending laterally 4teyo'nd the Wheels Il and l', as indicated at (i and ti and revoluloly suiiportingj the two side cultive tor sprockets 'i' and 7. The said side cuitivater sprockets are supported vertici-il shafts 72 and 73. The upper portion 8 of the frame of the cultivator is attached to e handle yoke '9 end supports the countershaft l0, and .a handle lll. is rigidly snpported by the yoke in any suitable manner. Connected to the handle 526 'brace 35' which extends horizontally Liorward and which is secured to the upper end of the cylinder of the engine Carried by seid brace is e tank 28 carrying the nel tor 95 the engine. The said brace on its ,lower aee carries a battery hon 29 in which are er ranged the hatt-cries for the engine.

'Supported in the trarne 3, intermfiiate the slirrockets 7 and 3" is a verticel shaft 13, which has el. its loi end the .spi-u "-0 which is in a horizo Imi special-:ets i .ai/id T and sides et the large are designed to scratch ,the soil. The npper end of the shaft 13 isi-provided with a beveled gear 14, meshing with thebeveled geacl, whihh i's,loosely mounted upon the shaft y1O,. `I 1o'oslely' mounted uzpon t shaft 10 is a sprocket 18, around which a ciain 19 passes, and said chain passing around a sprocket 20 carried by the axle. By this structure itkwill be seen thatthe axle 2 is driven forward for propelling the cultivator ,tor-` Ward. The counter shaft 10 is provided with a pulley 21 rigidly secured thereto and over which passes a elt'22 driven by the pulley Q3 carried by he engine shaft.

By this structure it will be seen that the the clutch member 24 and 'a lever or rod 25 secured to the opposite end, which extendsalong the side` of the' handle 11 in easy reach of the operator. Keyed upon the shaft 10 on the opposite side of the beveled gear l5 is a. clutch member 24', which is longitu dinally movable and adapted td interlockl '.with the clutch member carried by the xsprocket 18 and whereby the sprocket is coupled or uncoupled to theshaft for driving the axle 2 and causes the cultivator to move forward. Pivoted to the frame 3 vis a bell-crank lever B1, which has one end engaging the clutch 24 and the opposite end `secured to a lever or rod 25 which extends along the side of the handle ll'in easy reach of the operator.

By the structure herein described, it will be seen that by moving the clutch member 24 out of engagement with the sprocket 1S, thev Vforward motion of the cult-ivator is stopped but the cultivator chain continues to move to more thoroughly cultivate the ground in any desired spot, and it thus beco nes possible to operate the cultivat'or veh 'le back and forth by hand independent of tle motor;

'While I have shown and described the cultivator as being propelled and driven by a gas engine, it will be understood that an electric -motor may be readily used'.

Having thus described my invention, what I claim and desire to secure by Letters Patent is:

1. A cultivator, comprising a vehicle, a

motor carried by the vehicle, cultivating eleinents carried by the vehicle, means carried by the vehicle for operating the latter either by the-motor or by hand and means for operating the vehicle and cultivating element independent ofA each other.

' 2. A cultivator comprising a vehicle, a motor carried by the vehicle, means for manually controlling and operating the vehicle independent of the'motor, soil cultivating elements supported by the vehicle and operated by the motor and means for operating the soil cultivating elements independent of the operation of the vehicle.

3. A cultivator comprising avehicle, a motor carried by the vehicle, transverse horizont-ally operated cultivating elements carried by the vehicle movable thereon and continuously in-cultivating position and op erated by the motor.

4. A cultivator, comprising a vehicle, a motor carried by the vehicle, an endless belt upon vertical axis and operated horizontally and transversely the track of thevehicle, soil lcultivating elementsattached to the belt,

whereby they engage the soil during their entire travel, and means whereby the eultivating element may be raised and lowered.

5. A cultivator, comprising a vehicle., a motor carried by the vehicle, cultivating elements carried by the vehicle and operated at a vdifferent speed to that of the wheels of the vehicle, and means carried by the vehicle forv operating the latter by the moto-r or by hand.

6. A cult-ivator, comprising a vehicle, a motor carried by the vehicle, soil cultivating elements carried by the vehicle, and means carried by the vehicle for manually operating the latter independent of the motor` In testimony whereof I hereunto ailix my signature in the presence of two Witnesses.
